Gefell MT71S

The MT 71 S condenser microphone equipped with our proven large diameter membrane capsule features outstanding performance, a high sensitivity and a improved signal-to-noise ratio.

The MT 71 S guarantees a particularly clean and colourless sound reproduction. lt is well suited for instrumental and vocal soloists in radio and television broadcasting and for accurate productions.

The pressure gradient transducer is a dual capacitor design using a single brass back plate and two large diameter gold plated plastic membranes.

The cardioid pattern exhibits a smooth treble boost rising which peaks at about 4 dB in the range of 7 kHz. This response coupled with a slight roll-off at low frequencies is what gives the microphone its legendary "presence". The direction of maximum sensitivity is radial to the grill, i.e. side addressed.
The newly developed transformerless circuit design substitutes the previous transformer by a symmetrical output stage yielding superb transient response combined with high RFI rejection. The circuitry also achieves wider dynamic range by lowering the self noise floor and increasing the headroom for loud signals.
A 10 dB attenuator is installed to reduce the sensitivity of the microphone when placed near extremely loud sound sources. And, a low frequency roll-off switch will reduce the proximity effect when dose miking.

The microphone is equipped with a 3-pin XLR connector fitting to a microphone cable, e.g. C 70.
The MT 71 S uses 48 volt phantom powering according to the international standards DIN 45596 and lEC 2 68-15.

lt is available in a black matte or satin nickel finish.
